Experiments designed to determine the effects of feeding graded levels of xylanase to 10-kg pigs (exp. 1) and 1-d old broiler chicks (exp. 2) are presented. Pigs received diet composed of corn, rye, wheat, and SBM for 28 d, whereas chickens were fed diet composed of rye, wheat, and SBM for 21 d. Six dietary treatments consisting of a control diet or control plus xylanase (in units kg-1) at 400, 800, 1600, 3200 or 32 000 were fed. Graded levels of xylanase had no effect on growth performance of 10-kg pigs. There were diet and age effects (P < 0.05) on digestibility of DM, CP, and Ca in pigs. Linear and quadratic responses (P < 0.05) in final weight, weight gain, and gain:feed of broiler chicks to graded levels of xylanase were observed in exp. 2. In exp. 2, the effect of xylanase became apparent (P < 0.05) at 800 U kg-1; there were no differences in response to xylanase at 3200 and 32 000 U kg-1. In conclusion, xylanase improved growth performance in 1-d-old broilers fed a diet composed of rye, wheat, and SBM but not in 10-kg pigs that received a diet composed of corn, rye, wheat, and SBM. Key words: Broiler chicks, non-starch polysaccharides, pigs, xylanase

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

This study was carried out to evaluate the effect of 45 minutes Boiled Mucuna Seed Meal (BMSM) on the growth performance and nutrient digestibility of broiler finisher chicks. In a four-week feeding trial, three hundred and fifteen (315),4-week old broiler chicks were  randomly allocated to five experimental treatment diets in a completely randomized design (CRD). Each treatment was replicated thrice having twenty-one (21) birds per pen. Boiled Mucuna seed meal was prepared and fed in graded levels of 0.0% (control diet), 10.0%, 20.0%, 30.0%, and 40.0%BMSM. Feed and water were given to the birds ad libitum. The parameters measured and calculated include final weight, weight gain, feed intake, feed to gain ratio and feed cost per kilogram gain. Digestibility of dry matter, crude protein; crude fibre, ash, nitrogen free extract and ether extract were also determined. The data collected were subjected to analysis of variance (ANOVA). The results showed that dietary levels of inclusion of BMSM had significant (P<0.05) effect on these parameters. The final weight, the weight gain and feed intake of the birds fed 0.0%, 10.0% and 20.0%BMSM were statistically (P>0.05) similar and significantly (P<0.05) higher than those of other treatments. Cost of feed per birds and feed cost per kilogram gain were lower for all BMSB diets.Digestibility of nutrients was better for the birds fed the control,10.0 and 20.0%BMSM based diets. It was concluded that inclusion of BMSM in the diets of broiler finisher chicks up to20% has no deleterious effect on growth performance and nutrient digestibility of the birds.     Cette étude a été réalisée pour évaluer l'effet de 45 minutes de farine de graines de Mucuna (le 'BMSM') bouillie sur la performance de croissance et la digestibilité des éléments nutritifs des poussins finisseurs de poulet à griller. Dans un teste d'alimentation de quatre semaines, trois cent quinze (315), poussins de poulet de griller de 4 semaines ont été aléatoirement attribués à cinq régimes expérimentaux de traitement dans une conception complètement randomisée (le 'CRD'). Chaque traitement a été reproduit trois fois avec vingt et un (21) oiseaux par enclos. Le repas bouilli de graine de Mucuna a été préparé et alimenté dans les niveaux classés de 0.0% (régime de contrôle), 10.0%, 20.0%, 30.0%, et 40.0%BMSM. L'alimentation et l'eau ont été données aux oiseaux ad libitum. Les paramètres mesurés et calculés comprennent le poids final, le gain de poids, la prise d'aliments pour animaux, le rapport alimentation/gain et le coût des aliments pour animaux par gain kilogramme. La digestibilité de la matière sèche, protéines brutes; des fibres brutes, des cendres, de l'extrait sans azote et de l'extrait d'éther ont également été déterminés. Les données recueillies ont fait l'objet d'une analyse de la variance (ANOVA). Les résultats ont montré que les niveaux diététiques d'inclusion de 'BMSM' ont eu un effet significatif (P<0.05) sur ces paramètres. Le poids final, le gain de poids et la prise d'alimentation des oiseaux nourris 0.0%, 10.0% et 20.0%BMSM étaient statistiquement (P>0.05) semblables et significativement (P<0.05) plus élevés que ceux des autres traitements. Le coût de l'alimentation animale par oiseau et le coût de l'alimentation par kilogramme étaient inférieurs pour tous les régimes BMSB. La digestibilité des éléments nutritifs était meilleure pour les oiseaux alimentés le contrôle,10.0 et 20.0% BMSM régimes à base. Il a été conclu que l'inclusion du BMSM dans l'alimentation des poussins finisseurs de poulet de gril jusqu'à 20 % n'a aucun effet délétère sur la performance de croissance et la digestibilité des oiseaux en matière d'éléments nutritifs.

This study was conducted to investigate the effects of dietary supplementation of Endoglucanase producing Bacillus subtilis sp. fermented product (EBFP) on growth performance and meat characteristics in broilers. A total of 480, 1 day old ROSS male broiler chicks were obtained from a local hatchery and randomly allotted to 1 of 4 dietary treatments with 6 replicate pens consisting of 20 chicks. Three additional diets were prepared by mixing 0.1% of commercial cellulase, 0.1%, and 0.2% of EBFP with the control diet and all chicks were fed experimental diets and water ad libitum. Feed intake and body weight (BW) were recorded at 0, 3, and 5 week of the experiment. At the end of the experiment, birds fed a diet containing 0.1% of EBFP had the highest BW compared to birds in other groups (P > 0.01). During 0 to 5 week the experimental period, the dietary addition of 0.1% EBFP significantly increased (P > 0.01) BW gain that was higher than that of birds fed the diet in which only a commercial cellulase was added. No significant difference among treatments was observed in carcass weight, carcass yield, left breast, and thigh meat. These results suggest that dietary addition of cellulolytic probiotics may enhance growth performance compared with the single use of probiotics or enzymes.

The performance of broiler chicks fed on two common species of edible insects: African palm larva (Rhynchophorus phoenicis) and winged termite (Macrotermes bellicosus) in south east, Nigeria were studied using 135 day old Arbor acre birds. Three dietary treatments (T1, T2 and T3) representing Diet A (control: vital feed based fishmeal), Diet B (African palm larvae meal; APLM), and Diet C (containing winged termite meal; WTM), respectively, were used. T1 comprised of a standard feed of brand name ‘vital feed’ containing fishmeal which served as control while T2 and T3 both had insect meal: APLM and WTM, respectively, in place of fishmeal. Forty five broiler chicks were randomly assigned to each of the three dietary treatments at the rate of fifteen chicks per replicate and three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were subjected to similar husbandry and sanitation practices. Weekly record of feed intake, weight gain and linear body measurements were taken. Data obtained were subjected to ANOVA appropriate for completely randomised design and the differences between means were separated using least significant differences. The result showed that chicks fed with control diet based fishmeal (Diet A) had the highest feed intake compared to those fed Diet B and Diet C. Broiler chicks on Diet B however had the highest records in all performance indices (weight gain, feed efficiency ratio, specific growth rate, protein efficiency ratio and linear body measurements) investigated followed by Diet C and lastly Diet A. The study therefore recommends the use of insect meal for complete or partial replacement of fishmeal in poultry feed formulation.

A 49 day feeding trial was conducted to determine the effect of biologically upgraded cocoa pod husk meal (BCPHM) on the growth performance, haemato-biochemical indices and antioxidant status of broiler chickens. Three experimental diets were formulated at both starter and finisher phases in which BCPHM was added as an active feed ingredient at 0, 10, 20% and designated as diets 1, 2 and 3 respectively. One hundred and fifty day old Marshal broiler chicks weighing 39±2.5g/bird were allotted to 3 dietary treatments (10birds/replicate, 50birds/treatment) in a completely randomized design. The Average daily weight gain (ADWG), total weight gain (TWG) and final body weight (FBW) of broiler chicks fed diets containing 10% BCPHM was significantly (p˂0.05) higher than that of control and diet containing 20% BCPHM at starter phase. At finisher phase, the values of ADWG, TWG  and FBW were at par with that of control. Feed Intake was seen to increase as BCPHM increased in the diet at finisher phase. Carcass traits, relative internal organ weight, haemato-biochemcal indices of broiler chickens were similar across dietary treatment. Superoxide dimutase (SOD) and Catalase (CAT) of birds fed control diet were significantly (p˂0.05) higher than those of birds fed BCPHM based diets. Ten percent dietary inclusion of BCPHM appears optimal in broiler diet since beyond this level growth performance declined.

Sixty (60) grower-finisher pigs (Landrace x Large white) were used to investigate the nutritional value of beniseed hull (BSH) as substitute for maize on performance, carcass, and organs characteristics of the experimental animals. Five experimental diets were formulated by incorporating BSH into basal diet to replace maize at 0, 25, 50, 75 and 100%; designated as T1 (control), T2, T3, T4 and T5, respectively. The experimental pigs were individually weighed and assigned to five dietary treatments of three replicates of four animals each in a completely randomized design. The animals were fed for 2 weeks pre-experimental period and thereafter for ten weeks during which data were collected. Feed cost per kg live weight gain (? 668.67) of the animals fed 0% BSH significantly (P<0.05) reduced to ? 620.06 (25% BSH), ? 527.24 (50% BSH), ? 509.74 (75% BSH) and ? 456.73 (100% BSH). The bled weight, scald weight, eviscerated weight, dressing percentage, bacon, fore hock, hind hock and tail were significantly (P<0.05) affected by dietary treatments. The biggest liver weight (2.27g/kg) obtained in the animals fed the control diet (0% BSH) reduced significantly (P<0.05) to 2.20 (25% BSH), 1.91 (50% BSH), 1.76 (75% BSH) and 2.00 (100% BSH). Variations obtained in the kidney weight (0.40 g/kg) of the experimental animals fed with 25% BSH-based diets were similar (P>0.05) to 0.38 g/kg in the control (0% BSH) with both significantly (P<0.05) reduced to 0.36 (50% BSH), 0.36 (75% BSH) and 0.32 (100% BSH), respectively. Beniseed hull (BSH) poses no health challenge to the pigs used in this study. There were reductions in the cost/kg and cost of feed per kilogram live-weight gain with increasing levels of BSH in the diets, the lowest being at 100% level of substitution; beniseed hull could economically and safely replace maize in pig's diets up to 100% level.

A study was carried out to look at the utilization of cowpea based diets on performance characteristics and haematology of broiler chickens.  Raw cowpea, dehulled cowpea, dehulled cooked cowpea and dehulled roasted cowpea grains were fed to broiler chickens in an eight week feeding trial. A total of two hundred (200) day old unsexed broiler chicks of Marshall strain were allotted into five dietary treatments.?Feed intake and growth were significantly (P < 0.05) reduced in birds fed raw cowpea and dehulled cowpea respectively. The feed conversion efficiency (FCE) and protein efficiency ratio (PER)  also followed a similar pattern. Non significant (P > 0.05) differences were however obtained in weight gain, FCE and PER of birds fed control diet and those fed dehulled cooked cowpea in this study. Birds fed dehulled roasted cowpea also had marginal reductions in weight gain, FCE and PER when compared to those fed dehulled cooked cowpea based diet. The haematological studies showed lower (P < 0.05) values of haemoglobin, red blood cells, packed cell volume and white blood cells of birds fed raw cowpea and dehulled cowpea respectively. The best significant indices in this study were however obtained in birds fed dehulled cooked cowpea.Bang. J. Anim. Sci. 2016. 45 (1): 62-68


The study investigated the effect of replacing maize with alternatives (white sorghum, red sorghum, grey millet and brown millet) on the growth performance and cost benefit of broiler chicken. A total of one hundred and fifty (150) day-old Aboica strain broiler chicks were purchased for this study and were randomly allotted to five dietary treatments. The five is caloric and is nitrogenous diets for both the starter and finisher phases were formulated with the test ingredients (yellow maize, white sorghum, red sorghum, grey millet and brown millet) as the main source of energy and were designated as T1, T2, T3, T4 and T5. Each treatment was further divided into three replicates with ten (10) birds per replicate. The parameters investigated were growth performance and economics of production. This study revealed no significant (p>0.05) differences in weight gain among all the treatment. Furthermore, it showed a significantly (p>0.05) lower cost of producing the four alternatives as compared to the control (maize) and higher gross profit. It was concluded that white sorghum, red sorghum, grey millet and brown millet can replace yellow maize without any adverse effect on the health status and general performance of broiler chickens.
